Origin of the term
In movie industry terminology, a sound track (two words) or just track
is an audio recording created or used in film
production or post-production.
Initially the dialogue, sound effects, and music in a film each has its own
separate track (dialogue track, sound effects track, and music
track), and these are mixed together to make what is called the composite
track, which is heard in the film. A dubbing
track is often later created when films are dubbed into another language.

The contraction soundtrack (one word) came into use with the advent
of so-called "soundtrack albums" in the early 1950s. First conceived
by movie companies as a promotional gimmick for new films, these commercially
available recordings were labelled and advertised as "music from the
original motion picture soundtrack." This phrase was soon shortened
to just "original motion picture soundtrack." More accurately
such recordings are made from a film's music track, because they usually
consist of the isolated music from a film, not the composite (sound) track with
dialogue and sound effects.
Soundtrack has since come to denote three different things: (1) the
recorded sound accompanying a visual medium such as a motion
picture, television
show, or video
game, (2) just the music in it alone, or (3) a genre of music
("soundtrack music" or "soundtracks").

The abbreviation OST is often used to describe the musical soundtrack
on a recorded medium, such as CD,
and it stands for Original Soundtrack; however, it is
sometimes also used to differentiate the original music are heard and recorded
versus a rerecording or cover
of the music. |
